INTRODUCTION When a web of these materials is unwound or rewound the web tension varies as the roll diameter of the material changes. Web tension must be maintained at a constant level to prevent wrinkles, sags, changes in width or thickness, or breakage of the web. In printing processes, variable tension causes a paper web to stretch or shrink, causing sudden register errors. This problem necessitates tension control. Tension sensors are mounted at both ends of a sensor roll. The tension controller can be operated simply using a stable proportional + integral action with a constant loop-gain circuit. This configuration provides both responsivity and stability regardless of roll diameter. The actuators include both an electromagnetic brake and a pneumatic brake for use when unwinding. The electromagnetic brake can be connected directly from the controller but the pneumatic brake must be used with an electro-pneumatic converter. Winding can be achieved using many systems, including an electromagnetic or pneumatic clutch, and electromagnetic coupling motor or a torque motor. Intermediate tension control can also be handled where necessary. About Nireco Tension Controllers Suppression of Hunting via Constant Loop Gain Circuit Instability is a frequent problem with tension control. The main source of this instability is the fact that in order to set the tension, it is necessary to change the brake torque, which is what is manipulated in order to control tension; but if too much leeway is given in brake selection, and a high-capacity brake is selected, then the output at small coil diameters could fall below the range of safe control. In general, the gain setting is constant, and has no relation to coil diameter. Thus when the coil is small, there is a tendency for the loop gain to increase, and for instability to result. Nireco reduces control instability (hunting) by using a tension controller with a constant loop-gain circuit that eliminates changes in loop gain due to changes in coil diameter. Increased Stability through Proportion + Integral Calculation There is some distance between the rewinding reel and tension sensor, and a certain amount of time to transmit tension waves between them is unavoidable. In other words, there is a slight but real amount of waste, and in addition, noise is generated in relation to the coil rpm. Consequently, stable control using integral (I) analysis alone is not feasible. Additionally, brake input changes in accordance with coil diameter, and so the offset with proportional (P) calculation alone is too large to use. Nireco tension controllers therefore employ Proportion + Integral (PI) calculation for stable tension control. T Tension setting Controller with constant loopgain circuit Caontroller output = brake input Brake D Rewinding reel 2 Tension Control System Tension value Torque Tension sensor Brake Tension Control System FEATURES Constant loop-gain circuit gives superio responsivity and stability Control circuit calculations are carried out by both proportional and integral operations to give rapid, precise responses. Exponential operations are used to maintain a constant loop gain regardless of variations in diameter. Therefore loop gain is always maintained at the right level, with high responsivity but no hunting. This system is extraordinarily effective when used with splicers, highspeed presses and in situations with high roll diameter ratios. Tension Controller with constant loop gain cuicuit Tension Output Diameter Previous tension controllers Tension Easy to use, simple to control Given start and stop contacts, the system can be controlled automatically. Anyone can operate it just by setting a target tension value. A sequencer is built in that gives an output value corresponding to the diameter when the systems stops. Tension indication available In addition to total tension, tension for a single side can also be sensed. Taper tension during unwinding can be set Output Diameter Tension control is possible for unwinding, winding and intermediate (infeed-outfeed) situations Various installation methods are accommodated to suit the operator's position Panel mounted, floor mounted, and wall mounted . Tension can be set from an external source The system can be applied to various actuators Pneumatic brakes, pneumatic clutches, pneumatic motors, electromagnetic brakes, electromagnetic clutches, torque motors, electromagnetic coupling motors etc. SAMPLE APPLICATION Web-fed offset printing press Tension Control Applications Unwind tension controller Infeed tension control 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

It supports a wide range of products, with any tension range. The MB Tension Sensor has long been a strong seller, since sales were launched 20 years ago. FEATURES Proven Track Record and Reliability Without bearings or similar mechanical contacts, and employing a non-contact detection method using a differential transformer, the MB Tension Sensor is highly responsive with low hysteresis. The compact size also requires little space for installation. Easy to Install The MB 05, 11, and 25 can be installed at any angle. Wide Selection of Sensors 1 Full range available, from low tension (50 N full scale) to high tension (10,000 N full scale) 2 All sensors have intrinsically safe construction. MB05 Overload Resistant The durable construction provides resistance to momentary overloads. MB11 MB25 MB Tension Sensor 6 Tension Control System MB33 Tension Sensor PRINCIPLE AND CONSTRUCTION To measure the tension, attach a MB tension sensor to 3 rollers arranged in a triangle (see figure at right). The relation between the tension "T" and the load "F" is expressed by the following equation. Wrap angle Roll weight Pillow block Sensor roll Tension T Load F Fulcrum 0 Load receiving plate Differential transformer Structure of MB Tension Sensor (this drawing shows model MB25) The figure above shows the structure of the MB tension sensor. When the web tension increases, the resultant force F of the tension acts downward on the pillow block on which the roll is mounted. Due to this load, a very small rotation occurs, starting from the fulcrum O. Since this fulcrum has a spring action, the rotary displacement is proportional to the resultant force F. This displacement is very small at the roll, and reaches a maximum at the core which is remotest from point O. This mechanical displacement is converted into an electrical value proportional to the displacement of the differential transformer. Since the displacement due to deflection of the fulcrum is proportional to the load, the electrical value produced is proportional to the load, the electrical value produced is substantially proportional to the tension ( ∝ load). Thus, the fulcrum and differential transformer determine sensor performance. Therefore, the fulcrum is machined by cutting, and its material excels in spring action (hysteresis and strength), while stress is at a sufficiently low value. The differential transformer also has a high oscillation frequency, and the temperature characteristics are excellent.

Basic Configuration 7 Tension Sensor MG TENSION SENSOR MG010, MG020, MG050, MG100, MG200 The MG Tension Sensor was designed to be used with a tension controller or tension meter. It features compact and rigid construction, high accuracy, reduced temperature drift and high response. FEATURES With excellent temperature characteristics, the compact size saves space as well. Additionally, non-contact detection using a differential transformer yields improved precision. PRINCIPLE AND CONSTRUCTION MG Tension Sensor When web tension is applied to the MG tension sensor, the movable core of the differential transformer moves about the spring fulcrum 0. That change in core position causes the differential transformer to vary the electrical signal. Figure 1 shows the structure of the MG Tension Sensor. When web tension (T) is applied to the sensor roller, load (F) of tension acts downward on the load bearing plate. Due to this load, the load bearing plate rotates minutely about the fulcrum point 0. The torque generated bends the spring fulcrum. This small displacement of the load bearing plate reaches a maximum at the opposite side of fulcrum point 0, where the core of the differential transformer is installed. The mechanical displacement of the core is converted into an electrical signal by the differential transformer, using the change in mutual inductance. The signal is sent to a tension controller or a tension meter. The relationship between tension (T) and load (F) in the structure, as shown in Figure at right is expressed by the following equation.

Tension Control System MC05, MC20, MC30 The MC tension sensor is a force converter designed especially for tension controllers or tension meters. It is a high-precision instrument suited to high-speed lines. FEATURES High spring-steel characteristics provide a high resonance point, ideal for a high-speed line. Load-displacement is extremely small, making it effective for single-sided plastering of thin-web lines (e.g. film and aluminum foil). Use of a simple mono-block construction provides excellent precision, linearity, and hysteresis. MC05 Use of a stopper gives the construction good tolerance to overloads.

TABLE OF MODELS Not provided Basic Configuration 13 Tension Controller FUNCTION 1 Tension Indicator 3 Sequence Operation This section amplifies the signals from the No. 1 and No. 2 sensors of the MB Tension Sensor and adds them for display at the tension indicator. The amplified signals are also then fed to the PI control section. This operation applies proper timing to the controller operation by START and STOP timers. The start timer is used to set the proper waiting time (variable between 0 to 20 seconds) on start for the machine operation to enter into automatic operation. The stop timer is used to determine the duration of the stopping break (variable between 0 to 20 seconds) in proportion to the coil diameter on stopping of the machine. 2 PI Control Section and Exponential Operation The signal output from the adder section is compared with the "set" signal. If there is a deviation between these two signals, the PI section performs operations to reduce the deviation. These operations are both P (proportional) and I (integral). Integral action eliminates "offset" (Target value and detected value should not match), providing the exceptional stability of the system. The function of exponential operation is to maintain the loop gain constant, regardless of changes in web roll diameter. Therefore, better response and stability can be maintained. 4 Current Amplifier Section When the actuator used is an electromagnetic clutch or brake, the output signal current is amplified (0–4A)before it is transmitted. When a pneumatic brake or clutch is used, the output of 4–20mA is converted into an electro-pneumatic air pressure of amplified flow for transmission to the clutch or brake.

The tension is measured by tension sensors installed on both sides of the roll. Therefore, not only the total tension of the web, but also the tension on either the right or left side of the web can be obtained. GENERAL The Tension Meter TM140 is designed to measure the tension on a running web in the manufacturing and processing lines of webs such as paper, film, rubber, textile, etc. The tension is meaasured by tension sensors installed on both sides of the roll. Therefore, not only the total tension of the web, but also the tension on either the right or left side of the web can be obtained. Tension Meter TM140A (analog indication) FEATURES Two display methods are provided: analog and digital Tension meter ● TM140/A (analog display) ● TM140/D (digital display) Compact panel mount type (wall mount or shelf mount possible). A variety of output terminals are provided as standard. ● Measuring output (0 to 10 V) for each of TOTAL, No. 1 and No. 2. ● Current ● Voltage Tension Meter TM140D (digital indication) output for control (4 to 20 mA) output for control (0 to 10 V) Many kinds of tension sensors from low tension (50N FS) to high tension (10000N FS) are available. Measuring output terminal on the front panel (0 to 10 V) Not only the total tension but also the tension on either the right or left side of the web can be obtained. The tension can be indicated twice by switching over the range switch, when the tension value is low. The analog tension indicator can be installed separately. Six AC power requirements are available. This allows the instrument to be used worldwide. Note A "G" is appended to the end of the model code for Tension Meter models which require the use of MC and CD type Tension Sensors. (eg. TM140AG, TM140DG.)

GENERAL Each channel's tension value can be displayed on the tension indicator or monitored on an externally-connected voltmeter or ammeter. The initial adjustment of the Tension Sensors can be conducted by selecting the relevant channel with the channel selection switches on the top of the unit and monitoring the tension value for the selected channel. FEATURES One tension amplifier unit has circuits and terminals for two circuits , so up to 16 channels can be used with the maximum eight units. (The external dimensions vary with the number of channels). MB, MG, CD, and MC Tension Sensors can be used.

By using magnetic powder as the medium for the transmission of torque and by regulating the coil's excitation current, it has been possible high performance, and an extended service life. GENERAL The brake's current-to-torque characteristic enables transmission torque to be generated from a small excitation current and, furthermore, this generated torque has an excellent linearity. Accordingly, the control of torque is possible over a large operating range. This type of brake does not generate the type of friction dust common with friction-plate brakes. Levels of contact noise are low; consequently, this product is highly suitable for silent-operation applications. Since deviations in input speed cause no resultant fluctuations in transmission torque, tension control for contact-slip operations can be easily achieved. Powder Brake NBS-5 NBS-10 FEATURES ●Allowable Shaft-End Load The following shaft-end load must be observed when the brake is being driven by a pulley or the like. Specifically, the actual shaftend load must satisfy the following equation. Powder Brake NBS-2.5 1. Table 1 is based on 1,800 rpm, with a bearing life of 6,000 H. 2.

The excitation Current-to-Torque characteristic 2 Torque Startup and Torque Annihilation Characteristics When an excitation voltage is applied to the coil, the excitation current which passes through that coil will increase in accordance with its tim constant. Furthermore, torque will be generated in the brake during periods of inactibity due to these increases in excitation current, and this torqu will ultimately reach saturation level. The coressponding torque startup time is represented by Tr. When the coil's excitation voltage is turned off, the corresponding electrical discharge will progress in accordance with the coil's time constant and the excitation current will reduce to zero. The brake torque will also drop as a result of these factors, and the time Tf at which it reaches 10% of the saturation torque is referred to as the "torque annihilation time." Torque Freewheel torque is generated when an excitation current is not flowing, and the factors which caouse this phenomenon are considered to be mechanical-type friction at locations such as bearing seals and also residual magnetism. The freewheel torque in NBS brakes is 1% of the rated torque or lower. Excitation voltge Current Voltage 2 Speed-to-Torque Characteristic As long as the excitation current is maintained at a constant setting, variations in input speed will not affect the brake's torque (this is referred to as the "constant torque characteristic"). Excitation current Current Accordingly, this type of brake is ideally suited to situations where the web is fed at a constant line speed from an unwing coil operating, and where the coil diameter reduces over time, thus causing the brake's input speed to be increased. Since variations in the input speed do not lead to correspondeing changes in brake torque, tension control can be achieved with a high degree of both ease and stability. Input Speed-to-Torque characteistic Saturation torque Torque Period of inactivity Freewheel torque to to (unloaded) (unloaded) Totque Input speed Note: The data from figure above does not incorportion time-depndent elements. Basic Configuration 21 Brake & Clutch CHARACTERISTICS When continuous operation is carried out, heat which is generated as a result of slipping causes the temperature of the brake unit to increase. If this type of temperature increase is not maintained within a specific range during operation, performance can be impaired or, in certain cases, a breakdown may occur. the slip factor is used to define this permissible temperature range. Note, however, that even if the brake is operating within the permissible slip-factor range, continued operation will not be possible if the rated torque is exceeded. When a brake is being selected, the following items of data corresponding to machine-operationg conditions will be required. Line speed : V max, V min, (m/min) Coil diameter : D max, D min, (m) Tension Permissible slip torque (Nm) Permissible slip torque characteristic : Tmax, T min, (N) ■ Example of selection of a brake for unwinding: Line speed : V max = 100 (m/min) : V min = 30 (m/min) Coil diameter : D max = 0.80 (m) : D min = 0.11 (m) Tension Speed (Nm) : T max = 140 (N) : T min = 60 (N) 3 Slip Factor Slip factor is the product of speed and torque, and consequently, this value will decrease as the speed decreases. In situations where an unwind coil is being used, the corresponding calculations should be performed using the working torque which corresponds to the maximum line speed. 1 Speed The permissible range of imput speeds for the brake is 10 to 1800 rpm. It is important to confirm that equipment in question is actually operating. Silip factor characteristic 2 Torque Use a torque ratio Slip factor (W) Brake & Clutch ● Brake Selection of 20 or less Speed (rpm) 22 Tension Control System Brake & Clutch ● Slip factor 4 Brake Selection A maximum working torque of 56Nm dictates that the NBS-10 is most suited for application. It is recommended that the maximum working torque be at least 50% of the brake's rated torque. The slip factor is 230W at an input speed of 40rpm, and, referring to the graph of continuous slip-factor characteristics for the NBS10, It can be seen that a slip factor of approximately 260W will occur at 40rpm. Accordingly, the NBS-10 may be employed in this situation. 5 Connecting the Unwind Coil and Brake via Gears If it is desired to connect the brake to an unwind coil via gearing, the corresponding gear ratio will be required during brake selection. ■ Example of selection of a brake for unwinding (Brake speed-Incrasing) Line speed : V max = 70 (m/min) : V min = 15 (m/min) ● Brake selection A maximum working torque of 31Nm dictates that the NBS-05 is most suited for application. During the subsequent consideration of slip factor, it can be seen that when the brake input speed is 56rpm, the slip factor is 179W. Using the slip-factor characteristic for the NBS-05, it can be determined that a slip factor of 204W will occur at 56rpm; consequently, the NBS-05 may be employed in this situation. ■ Example of selection of a brake for unwinding (Decelation of brake) Line speed : V min = 60 (m/min) Coil diameter : D max = 0.80 (m) : D min = 0.11 (m) Tension Coil diameter : D max = 0.80 (m) : D min = 0.11 (m) : T max = 140 (N) : T min = 60 (N) Gear ratio : V max = 180 (m/min) Tension : T max = 70 (N) : T min = 30 (N) : G2 /G1 = 2.0 Gear ratio Note: Refer to figure below Coil : G2 /G1 =0.5 The above apply to the same formula as the previous example. ● Speed N max = 260 (rpm) N min = 12 (rpm) Brake G1 = No. of gear teeth on the brake side G2 = No. of gear teeth on the coil side η = 0.9 (gear efficiency) ● Speed ● Torque τ max = 62 (Nm) τ min = 3.7 (Nm) ● Slip factor N = 36 (rpm) P = 230 (rpm) ● Brake selection ● Torque A maximum working torque of 62Nm dictates that the NBS-10 is most suited for application. Using the slip-factor characteristic, it can be determined that a slip factor of 260W will occur at 36rpm; consequently, the NBS-10 may be employed in this situation. Basic Configuration 23 Other Tension Control Methods Automatic Paster Tension Controller AUTOMATIC PASTER TENSION CONTROLLER TC900V This tension controller is equipped with a function which eliminates tension value changes due to base paper mass during automatic splicing, enabling trouble-free high-speed splicing. GENERAL This section describes the air-brake method of operation. The controller's output signal is sent to the air brake of the rewinding reel via EN40 (see Auto Booster Configuration drawing). When splicing, a reel-change signal is sent to the controller and switching valve, automatically initiating a sequence to switch the controller output to the new reel, and at the same time bringing the old reel to a fast halt by applying the halt brake via air pressure from the pressure-relief valve. The torque level of the new reel is uniquely set by the tension setting and initial rewind diameter. Note that a bumpless circuit is employed for smooth splicing. 1. Tension Value Time 2.

GENERAL The TDR 1240 features air-cylinder pressure that changes in relation to the dancer roll position, and adjustable air-pressure change gain. Conventionally, air-cylinder dancer-roll control would use the same tension control regardless of the dancerroll position. The TDR 1240, however, allows the dancer roll's return to center position to be sped up. This has a damper effect on the air cylinder, allowing for more stable tension control. As this absorbs sudden fluctuations in tension during paper feed and the like, it is particularly well suited to lines that operate intermittently. For brake control Output signal Tension meter rated tension 4 ~ 20mA For cylinder air pressure control 0 ~ 10V 4 20mA 4∼ 50/100/200/500/1000/2000/3000/5000/10000N 0 ~ +50˚C Ambient temperature 6㎏ Weight Power supply AC100, 0,110 0,120, 0 200, 0,220 0,240V 50/60Hz FEATURES Set tension (cylinder air pressure) with ease.

The roll diameter is calculated by using a signal from a gate generator mounted on the winding/unwinding reel, and a control signal corresponding to the change in the roll diameter is delivered. GENERAL Non-contact detection of roll diameter The roll diameter is detected without any contact being made using a gate generator attached to a winding/unwinding reel. Therefore, the material is not exposed to damage. Easy to operate It is operated just by setting the roll radius and the web thickness. Stop output circuit incorporated A stop output signal is generated when stopping an unwinder. The reel is stopped without slackening the web. Applicable to various brakes/clutches It is available with voltages of 0 to 10V and currents of 4 to 20 mA for control outputs.

The roll diameter is calculated by using signals from two generators mounted on the winding/unwinding reel, and a control signal corresponding to the change in the roll diameter is delivered. GENERAL The roll diameter can be measured The roll diameter is indicated on the indicator while a signal of 0 to 5 V is issued. The TCD050 can be used for other applications such as external taper signals for a closed-loop controller. Not necessary to use gears The roll diameter is calibrated internally. It is not necessary to use gears between the measure roll and the pulse generator. The sequence control makes operation easy Since a stop signal that is proportional to the roll diameter is output when the line stops, the web is prevented from slackening. The re-start level allows smooth re-starting because the stop level immediately before the line stops is stored. In addition, the start level can be set manually with the manual VR by resetting this stored stop level with the reset contact. Applicable to various brakes/clutches The control output is available at a voltage of 0 to 10 V and a current of 4 to 20 mA. Using them, the TCD050 can control an electromagnetic brake/clutch and an air brake/clutch. Taper tension can be controlled In addition to the constant tension control, the taper tension can be controlled. Tension Controller TC050 Compact unit This compact unit can be panel-mounted. It can be easily installed in the control panel. Non-contact detecting system The non-contact detecting system allows the TCD050 to measure the roll diameter without causing any damage. In addition, it is not necessary to make a roll space for attaching a sensor, which is required with other control systems.

SEQUENCE CONTROL The TCD050 automatically controls web tension using a reset contact signal and a stop contact signal for the machie. The sequence is as follows. 1. The reset (RESET) contact is made to reduce roll slip at the same time when th machine starts, and the output becomes the start level that has already been set with the manual VR. 2. The output becomes the control level to control the tension after the winding/unwinding reel has rotated four turns. 3. The output becomes the stop level when the stop (STOP) contact is made at the same time as the machine stops. 4. The output becomes the level immediately before the machine stops by turning off the stop contact after the roll has stopped. 5.

Determine the ones to use according to continuous slip efficiency, maximum torque and maximum and minimum revolutions. As a general guideline, the ratio of maximum torque/minimum torque for a single brake and clutch should be less than 20. Use multiple brakes or clutches if this ratio would be exceeded. 1.
